Container for holding powdery material

The invention relates to a container for holding powdery material, preferably detergent or similar.

In particular, cylindrical containers for holding detergents in powder form are known, the containers consist of a cylindrical body with base, removable lid and handle for transport.

The well-known containers, which have a fairly large capacity and can hold quantities up to 5 kg are difficult to manufacture, their manufacturing costs are accordingly high and, moreover, these cylindrical containers can only be stored or transported in a relatively bulky manner will. Another disadvantage arises when filling the known containers due to the unfavorable fastening of the handle.

The invention is based on the object of creating a container of the type mentioned at the outset that can be manufactured cheaply and can be stored or transported in a space-saving manner. According to the invention this object is achieved in that the container consists of an assemblable structure made of a foldable material which can be shaped into a rigid body by means of suitable reinforcing elements.

it consists of a single foldable part having longitudinally folded bending folds, a pair of rigid ones Frame structures, one of these frames forming the floor and the other the top surface, the latter with the handle for transport and a funnel for filling or the emptying of the container is equipped, and a lid, which is preferably by means of pressure on the upper frame part is attachable. The cover is placed in such a way that the bendable or foldable casing part has two basic configurations can, namely a flat one in which the empty container is stored and thus requires a minimum of space, and a . relaxed or working configuration that the container assumes when the rigid frames are deployed.

The basic concept of the invention leaves a lot of room for design variants, be it in terms of the material from which the shell part and frame are made, or in terms of the geometric one As far as the shape of the container is concerned, this geometric shape in any case corresponds to the contours of the frame must correspond.

An advantageous embodiment which takes up the space of the Composable container as much as possible, is that of a prism with an octagonal base.

According to an advantageous form of manufacture, the casing part of the container is made from a single cardboard part by means of punching produced, which has fold lines that delimit the respective lateral surfaces and according to which the shell part accordingly is folded to the contours of the base.

Each of the frame parts consists of a main part, which represents the bottom of the container bottom and thus a flat surface

909886/0773

is, however, is interrupted in the cover by the filling or emptying opening. The main part is bordered along its ümfanges with a side wall which has a groove that is also along the circumferential line of the main part. The jacket contour is inserted into this groove so that jacket and Bottom part form a rigid connection.

The invention is explained in more detail below with reference to the drawing. In the drawing shows:

The punched cardboard part A has fold lines 10, 12, 14, 16, 18, 20, 22 and 24 parallel to one another. The height of the collapsible part B from which the part A is folded, let h. It is not necessary that this part be made of cardboard; any other suitable material can be used for this.

The fold lines delimit the following outer surfaces: C and D

the front or rear lateral surface; F and G the smaller side surfaces and H, L, M and N the broken edge surfaces. the Adhesive strip 26 is glued in area 28 of surface C and thus gives the jacket part its prismatic shape.

the upper side of the part A, whose purpose is still

The cardboard part A, which represents the outer surface of the shell of the body B, is also used during the punching process with the inscriptions, such as product information, company logo, etc. printed.

In the form B ₁ , the part 3 requires the least space and is therefore ideally suited for storage or transport. In the unfolded form B ₂ according to FIG. 4 and when the rigid frame is put on, as will be explained below, the container can be filled with powdery material, preferably washing powder.

Referring to the remainder of the figures and primarily to FIG. 5, another fundamental characteristic is and although the prismatic shape P of the container can be seen.

The composable geometric body consists of the punched cardboard part B, which is punched out of a single surface A, from the lower rigid frame Q ₁ , which forms the bottom of the container P, from the upper rigid frame Q ₂ , which is with the handle 34 and the filler opening 36 is equipped, and from the lid 38, which the Einfüllbzw. Emptying opening 36 closes.

The cover 38 is provided with a flange 42 and a lifting tongue 40.

The collapsible part B can thus assume two basic configurations, namely the folded B ₁ , in which the part B can be stored and transported in a space-saving manner, and the unfolded B ₂ or B, which represents the actual prismatic body, whereby this shape is achieved, when the lower portion 44 is connected to the frame Q ₁ and the upper portion 46 to the frame Q ₂ . The joining of the frames Q ₁ and Q ₂ with the part B give the body support and form the actual container P, which in our case assumes a prismatic shape, the edges H, L, M and N of which are beveled.

The lower frame Q ₁ , which forms the bottom of the container P, has a flat surface 48 which, along its circumference, is provided with a side wall 50 at right angles to the plane 48. The side wall has a groove 52, the course of which also runs along the circumference of the plane 48. The lower zone 44 of the collapsible part B is pressed into this groove, it being possible for the connection to the groove 52 to take place by means of a hermetically sealed adhesive connection.

Of course, the part 44 with the frame Q ₁ can be connected to one another in any desired manner, for example by means of sealing, stapling, etc., provided, however, that this connection prevents the powdery material contained in the container from escaping.

The inside 54 of the side wall 50 is in the upper area 56 designed conically so that the pressing between the part 44 and the groove 52 is facilitated.

The frame Q ₂ is identical to the frame Q _{1 in} terms of its structure. This frame is also provided with a side wall 51 along its circumference and here, too, the inner side 55 is conical in the upper region 57 in order to

909886/0773

Pressing the groove 59 into the upper region 46 of part B to facilitate.

On its longer sections 61 and 63, the groove 59 of the side panel 51 is in the middle 65 of the sections mentioned interrupted so that a reinforcement in the upper frame Q can be used; this reinforcement takes pins 67 and 69 of the handle 34.

The handle 34 is attached to the upper frame Q _{2 in a very simple manner.} The pins 67 and 69 have an oval head 71 which is pressed into the elongated hole 73 of the full section 65 of the side panel 51. The diameter of the elongated hole 73 is smaller than that of the oval pin head 71. The elongated hole axis runs vertically.

To insert the pins 67 and 69 into the elongated holes 73, the handle 34 must be bent downwards (see FIG. 5), because then the pin head axis 71 is parallel to the elongated hole axis 73. In this position, the pin heads 71 can be inserted into the elongated holes 73 of the frame Q _{2 are} pressed in. When the handle 34 is brought into the holding position again (see Figures 6, 7 and 8), the pin head axis 71 is transverse to the slot axis 73. In this way, the seat of the pins 67 and 69 is secured in the slots 73, ie the connection between Grab handle 34 and frame Q ₂ is made.

When the handle 34 rests against the drop side 51 in the lowered position, the filling opening 36 cannot be blocked by the same will.

The upper frame Q ₂ is connected to part B by gluing the upper area 46 into the groove 52. In this way, an absolutely safe and hermetically sealed connection between parts Q ₂ and B is established.

After the centers 65 of the frame Q _{2 have} the reinforced side wall parts, the upper area 46 of the part must

909886/0773

B be provided with the already mentioned incisions 30 and 32, so that the edge 77 up to the point of contact with the part 79 the groove 52 can be brought.

As already mentioned, the frames Q- and Q, can be assigned to any Connected to part B, e.g. by means of sealing, sewing, staples, etc.

With 81 are the labels, product information, company logo or the like, which are printed directly on the lateral surface B during the punching process.

The container is completed with the lid 38 which is pressed into the filling opening 36 by means of pressure. So that the lid does not fall through, it has a bead along its circumference 42 provided.

The manufacture of the container is described below.

The collapsible part B is punched out of part Ά. During this punching process, the outside of part B is printed at the same time. Then this part is along its Folded the fold line and the adhesive strip 36 with the area 28 glued. Now part B is still folded up (see Fig. 2 and 4), this configuration being ideally suited to store the part. Later the folded parts are used as packaging containers for powdery material Supplied to consumers.

The space required for the folded part of the container is 1/8 of the actual container volume; the advantage of Storage or transport is obvious. For example, 250,000 folded container parts take up the same space as 32,0OO unfolded container.

The frames Q ₁ and Q ₂ are manufactured separately, for example from plastic; the same applies to the handle 34. The storage of the frame also takes up little space

909886/0773

a, after the frames are all the same and provided with a conical bottom part, so that these bottom parts into one another can grip, i.e. these frames can be stacked stably.

The final assembly of the container, which can also be done by machine, is carried out as follows: The area 44 of the folded part B is _{pressed into the groove 52 of the lower frame Q 1} and glued. Then the area 46 is pressed into the groove 52 of the upper frame Q ₂ and also glued. In this way, the shell part B is formed from its folded configuration B ₁ into a rigid container which is able to support the weight of the received powdery material.

The presence of the beveled edges that create the surfaces H, L, M and N reduces the bulk of the container, which has a prismatic shape with an octagonal cross-section instead of a cylindrical shape. Of course he can Containers have any geometric shape, provided that they can be folded of the shell part is retained.

The fully assembled container is placed over the filling opening 36 filled as follows: The handle 3 4 is swiveled until it rests against the side wall of the upper frame (see Fig. 5) and thus does not in the least hinder the filling process, as is the case with containers, their handle is attached to the outer walls. Finally, the container is closed with the lid 38 and the powdery material comes neatly packaged to the consumer.

As already indicated, the container material can be any, but the prerequisite is that the frames Q ₁ and Q _{2 have} the required rigidity and the part can be folded. The connection methods between part B and the frame can also be of any type, but it is necessary that the connection
